It was alarming when my daughter called me today that the result of her check up for her leg problem that caused her limping style of walking was due to the femur bone’s death – due to not receiving enough blood supply. The doctor suspected that it was caused by post natal trauma. I researched the subject and found this:
Osteonecrosis occurs when part of the bone does not get blood and dies. After a while the bone can collapse. If this condition is not treated, the joint will deteriorate and this will become severe arthritis.
Osteonecrosis can be caused by disease, or a severe trauma, such as a break or dislocation, that affects the blood supply to the bone.http://www.nlm.nih.gov/medlineplus/ency/article/007260.htm
So, I guess Osteonecrosis is the culprit and bone grafting is the remedy recommended by the doctor due to her age. Hip replacement is a very good alternative but it can last only until 10 years. So, if she’s going to have that option at 25, she has to do it again when she reaches 35. The purpose of bone grafting is to delay the total collapse of the bone since it cannot be repaired anymore at stage 3. I am just hoping that she will have the dedication to trim down as much as she can – to make it easy for her legs to bear the weight of her body.
